RAZOR BLADE WRAPPER Filed Dec. 15, 1957 1N VENTOR.

ATTORNEYS Patented Feb. 21, 1939 UNITED STATES PATENT" FFiCE 3 Claims.

This invention relates to a Wrapper for razor blades or similar keen edged implements and has particular reference to double edged safety razor blade and a wrapper therefor which is so con- 5 structed and arranged as to locate and maintain the cutting edges of the blade in spaced relation to the wrapper in order to prevent dulling of the blade edges.

The invention broadly comprehends a blade provided with means at its opposite end edges which are designed and intended to perforate the wrapper therefor so as to locate and maintain the cutting edges of the blade out of contact with the wrapper when folded into enclosing relation therewith.

More particularly the invention is directed to a double edge blade provided at each of its opposite end edges with one or more spurs which function during the enclosing of the blade in the wrapper to perforate the wrapper at the juncture of the end flaps with the main body thereof so as to hold the blade in fixed relation against relative movement with reference to the Wrapper whereby when the side flaps are folded thereover the juncture of the side flaps With the main body portion of the wrapper is prevented from contacting and dulling the blade edges due to shifting of the blade with reference to the wrapper.

With these and other objects in view the invention is more particularly set forth in the following specification and illustrated in the accompanying drawing wherein several preferred embodiments are disclosed by Way of example, while the appended claims cover variations and modifications which fall Within the scope of the invention.

In the drawing:

Fig. 1 is a plan view of a blade constructed in accordance with the invention.

Fig. 2 is a similar view showing the blade arranged and located in juxtaposition to the wrapper.

Fig. 3 is a similar view showing the end flaps folded over.

Fig. 4 is a similar View showing the final step in enclosing the blade.

Fig. 5 is an enlarged longitudinal section taken approximately on the line 55 of Fig. 4.

Fig. 6 is a plan view illustrating a modified form of blade.

Referring to the drawing by characters of reference, l designates a safety razor blade which, as illustrated in the present instance, is of the type having opposite longitudinally extending cutting edges ll. As is customary, the wrapper 52 which constitutes the inner wrapping for the blade is fashioned from sheet material such as Waxed or oiled paper and includes a rectangular body portion H which is of a width slightly exceeding the width of the blade Ill and of a length coinciding approximately with the length of the blade between its opposite end edges [4. The wrapper i2 is provided with end flaps I and side flaps Hi which are adapted to be folded inwardly into overlapping relation with each other and with reference to the main body portion l3.

It is obvious that the blade should be positioned and maintained in the wrapper I? so as to prevent the wrapper from contacting with and dulling the cutting edges H and various means have been devised for this purpose. The present invention, however, resides in the provision of outwardly projecting spurs if at the opposite end edges It of the blade which are adapted, during the wrapping of the blade, to form perforations [8 in the wrapper as the end flaps it are turned inwardly, it being understood that the blade and wrapper are relatively positioned prior to the turning in of the end flaps so that the cutting edges II are spaced from the side edges of the main body portion. As the end flaps are folded in and the spurs ll form the perforations l8 in the wrapper at the juncture of the flaps 15 with the main body portion l3, it will be apparent that the blade will be secured and retained in a fixed relation so that when the side flaps it are folded to overlapped relation, the blade is thus retained in a position to prevent contact of the cutting edges with the wrapper. It will thus be seen that the blade is provided with means designed solely for the purpose of forming means in the wrapper l2 which cooperates with the means on the blade to secure and retain the blade in the desired position.

While the blade in Figs. 1 to 5 inclusive is illustrated as provided with a single spur I"! at each of its opposite end edges l4, it is to be understood that the invention is not necessarily limited thereto and as illustrated in Fig. 6 of the drawing, the blade IDA is shown as provided with a plurality of spurs MA at its opposite end edges MA which will function in a similar manner for the purpose specified in connection with the form of. the invention shown in Figs. 1 to 5 inclusive.

What is claimed is:

:1. In combination, a blade having a longitudinal cutting edge and a wrapper therefor having a body portion of greater width than the blade and of a length coinciding with the length of the blade and side and end flaps foldable inwardly from the sides and ends of said wrapper, piercing means at the end edges of said blade adapted to perforate the wrapper as the end flaps are folded inwardly to retain the blade in fixed relation to the wrapper with the cutting edge out of engagement with the wrapper.

2. In combination, a blade having oppositely disposed longitudinal cutting edges and a wrapper therefor having a body portion of greater width than the blade and of a length coinciding with the length of the blade and side and end flaps foldable inwardly from the sides and ends of said wrapper, piercing means at the end edges of said blade adapted to perforate the wrapper as the end flaps are folded inwardly to retain the blade in fixed relation to the wrapper with the cutting edges out of engagement with the wrapper.

3. A blade and wrapping therefor comprising in combination a blade having oppositely disposed longitudinal cutting edges and opposite ends provided with outwardly projecting piercing spurs and a wrapper having a body portion of greater width than the blade and of a length coinciding with the length of the blade, side and end flaps foldable inwardly from the body portion of said wrapper, the end flaps when folded inwardly being perforated by the spurs to locate and retain the blade with the cutting edges spaced from the juncture of the side flaps with the main body of the wrapper.
